 # Duwa Programming Language (in progress)
-This project is an interpreter for the `duwa` language (Name still getting worked shopped), a language based on the Chewa Bantu language.
-This project is written in Golang.
-
-## Setup and Moni ku dziko
-Download the prebuilt binaries for your platform from the [release](https://github.com/sevenreup/duwa/releases)
-
-Create a new source file, `main.ny` (💀 for now the extension does not matter).
 
-Paste the following cool code
-
-```c#
-lemba("Moni Dziko");
-```
-Run you new application
+This project is an interpreter for the `duwa` language, a language based on the Chewa Bantu language.
+This project is written in Golang.
 
-```bash
-duwa -f ./main.ny
-```
+## Setup and Zowerenga
 
-## Zowerenga bwa?
-Documentation is on its way, stay on the cutting edge and freestyle your code.
+Follow the setup documentations at [official site](https://www.duwa.cphiri.dev)
 
 You can check out examples in `./examples` folder to quickly see what the language can do for now.
 
 ## Main Milestones
+
 - [ ] Create an initial interpreter
-    - [x] Lexer
-    - [x] Parser (Recursive descent parser)
-    - [x] Interpreter (Tree walking interpreter)

 - [ ] Language features
-    - [x] Basic data types (string, numbers)
-    - [x] arithmetic operations 
-    - [x] Control Flow (loops, conditional statements)
-    - [x] Functions
-    - [ ] Type checking (for now it does not strictly enforce types)
-    - [ ] Data Structures
-        - [x] arrays
-        - [x] dictionaries
-    - [ ] Input/ Output
-    - [ ] Error Handling
-    - [ ] Class support

+## Building
+
+### Prerequisites
+
+- TinyGo: If you are building the web assembly version you will need `TinyGo`, hers is the [setup](https://tinygo.org/getting-started/install)
+- GNU make (optional): Using make for building. You can build the project without `make`.
+
+### Builing/running
+
+You can build the project by running any of the build make tasks
+
+```bash
+make build
+```
+
+Or you can run go build directly
+
+```bash
+go build -C ./src/cmd/duwa -o ../../../bin/duwa
+```
+
+Running the project is the same either use make or go directly
